made a certainnew and useful Invention in Toy Motors, of which thefollowlng 1s a specification.

This invention relates broadly to motors and moreparticularly to toymotors.

The principal object of the present invention is an efficient toy motoreconomical to manufacture and characterized bya vibratiiw member towhich is attached a transmission band of light material which is passedaround a driving drum and with vthe free portion of the band between thedrum and the vibrating member disposed at an acute angle relatively tothe vibrating member. l

More specilically one embodiment of the present inventionl comprises anelectrically operated buzzer with a rotating drum mounted adjacent thearmature of the buzzer and with a light weight transmission band securedat one end of the said armature and encircling the driving drum with theother end anchored to a portion of the frame of the buzzer and with theparts so located that the transmission band leaves the armature at anacute angle.

A further object of the present invention is a. cheap eliicient andeconomica-l toy motor comprislng a buzzer with a relatively small drivindrum located close to the armature 0f the uzzer and with a light drivingband extending around the drum and with a tensioning member which maycomprise a. light coiled spring secured to the free end of the band tomaintain the band in frictional engagement with the drum.

. A still further object of the present invention is to provide a tovehicle with a motor as specified and wit a source of ener to operatethe motor, for example,` a smal dry battery, carried b the vehicle, andwherein provision is m e for disconnecting the source of ener from themotor to conserve the energy w en the vehicle has struck an impassableobject, such as in bumping into the side of a wall, etc.

wili be apparent that thel present in-` vention may be embodied inconstructions other than those specifically disclosed herewith and thatother and further objects of the present invention will in part beobvious ture thereof removed.

art it has been' cusand will in part be pointed out in the specificationhereafter wherein like parts are designatedrby like charactersthroughout the several figures of the drawings. j

Figure illustrates one form lof the present invention and shows themotor detached from any specific to v Fi re 2 shows t e motor attachedto a vehic e toy, or more particularly an electric locomotive with thecovering or superstruc- Heretofore in the to tomary to utilize smalsized motors carry: ing va field and a rotating armature and adapted tobe supplied with current through a suitablecommutator. The high cost ofsuch toys is largely due to the expense of the motor and insubstantially all cases electric toys of this character cost severaldollars.

Furthermore in view of the sliding contacts,

due to the' brushes on the commutator and vto the more or lesscomplicated character of such motors, there is a liability of the motorbeing disabled by the rough usage to which toys are ordinarilysubjected.

The present invention overcomes the didiculties of the known art byproviding an efficient small motor, very cheap and economical tomanufacture and of such construction 'as to stand rou h usa withoutbeing disabled and'which 1s provlded with a. very simple adjustment thatenables the same motor to run eectually on either direct or alternating1current so that toys may be driven by eit er battery or house currents.Referring now more particularly to Figure 1 of the drawings whichillustrates the motor detached'from any particular toy, the main frame 1which may be a punching from sheet metal is provided with openin 2 throuh which suitable rivets or screw solts may e applied for mountin themotor. This main breaker spring 9 which carries the armature 1 410. Thebreaker spring is secured to a portion of the main other securing means.ries a second binding st screw 11 which I is in direct contact wit themain frame in such manner that the main frame comprises the mediumthrough which the current is leadto the breaker spring and to the sparkgap. The foregoing construction is that of a well known signal buzzerand possesses no especial features of novelty except when in combinationwith the features herein after specified.

The main frame is provided with a U- l5 shaped extension 12 in which areformed the bearings for a driving drum 13. A- light weight transmissionband 14 comprising a "linen ta or the like is secured to the armature oft e buzzer and preferably is wrapped 2v around the driving drum and withthe ree `end of the tape attached toa coiled spring 15 which is anchoredin one of the openin 'i 16 in the lug 17 extendingufrom the main frameIt is to be noted t s lug carries a plurality. i of openings whichconstitute means for varying the tension on the spring,

l dependent on which o ning the spring is anchored in. This variation ofthe tension l' varies the speed of the motor. v.

The invention comprises more especially the combination of the old wellknown fbuzzer with a driving drum and a transmission band in such mannerthat when the armature of the buzzer is vibrated the drum *ll willrotate. This rotation is best secured by constructing the arts in suchmanner T e main frame car- \.that the transmission and or tape 14 leavesthe armature 10 on an acute angle 29. The y#angular relationship betweenthe transmission band and the armature causes a wh1pping motion to beimparted to the band and lgthis whipping motion is somewhat similar,.-'to transverse shaking the end f a rope which is attac ed at theother end to a post. 46 Such a motion sets up in the transmission bandboth transverse and lon tudinal waves. These waves contacting wit theperiphery of the driving drum cause the drum .7 to rotate toward the endof the band which 'yis connected with the armature. This in- 'jventionfurther contemplates thel construction and combination wherein theadjustment screw 8 for the spark gap may positioned in such manner thatthe vibrat 66 tion of the armature may be effected without openin thespark gap due to the elasticity l"o the reaker spring. Under suchadjustment it will be obvious that the armature may be vibrated b'ysupplying the electromagnet 3 with a pulsating current, forexample, theordinary commercial alternatin muri-ent. It is likewise obvious that thehrmature may be vibrated b adjusting the spark gap in such manner t atthe current is`broken each time the magnet is energized frame b suitablerivets or v lthe locomotive.

and under this condition the motor ma be operatd on a direit currertsuch as a a? teryo pro rvo anamlr` t will therefoip be seeanghat 'theppraseagconstruction is adaptable for use on either type of current..

Referring now to Figure 2 the motor is shown as mounted upon the frameof a toy electric locomotive and the shaft 18 on which the drivingdrum'is mounted comprises the axle for the drivin wheels 19 of The framea carries another pair of wheels 20 which support the other end of theframe of the locomotive. Preferably all these wheels areiianged and thethus may be constructed to run on toy rai s 21. `In this embodiment theframe `carries a small battery 22 which is connected with an insulatedbutton 23 that isadapted to cooperate with a switch head 25 mounted onthe end of a push rod 26 which is arranged to slide on the main frame 27and is constructed so that when the switchY head is pulled intoengagement with the insulated button the parts tend to retain thlsposition whereby one terminal of the battery is grounded to the mainframe. Since one terminal of the buzzer is 'also connected to the mainframe and the other terminal of the buzzer is connected directly withthe battery it will be noted that the push switch must be closed inorder that the current will flow through the electromagnet. When thecurrent is flowi the buzzer o rates to drive the locomotive. If the buer of the push switch contacts with an obstruction the switch 'will beopened and the current broken so that the battery is not discharged by orating the motor after the to as struc an immovable obstruction. is isparticularly desirable where the motor is uilt into to automobiles andsimilar constructions a ted to run over the carpet and to strikeurniture or side walls of the room.l u.

In view of the extreme simplicity lof the present motor, and the factthat it is adapted for direct drive to toys, etc., without. usingreduction gears, it is especiall adaptable for low priced toys and atthe same u' time the to constructions are 'sim lied so that the li e ofthe toy is extend beyond that of the more complicated devices. In Figure2 the adjustment screw for the spark break has been omitted and apermanent contact point 28 is provided on the contact plate 6. Where itis desired to run this toy` on an alternating current suitable shoes ortrolleys are provided and one terminal of the buzzer is connected to theinsulated butg ton and the other terminal is connected to thetrolley orthird rail so that the current may be introduced through the track intothe main frame of the device and from the main frame through theinsulated button to 3 the buzzer wheneasthe return circuit forA itsforce quickly and the tension of the ar-v mature spring tends to snapthe armature back quicker than the movement thereof during the power orull stroke. There 1s another element whic tends to -make the powerstroke the slower movement of the transmission band, and that is, thatas the band is graduall pulled taut the resistance to the pull of t eamature graduall increases. Whereas when the magnetic orces are on thedecline a very little slack in the band is suicient to accomplish therelease so that the releasing action Voccurs quicker than the powerstroke. The above "specified action produces a continuous creepin actionof the waves around the drum which is thereby continuously rotated.

I claim- 1. A device of the character described comprising incombination a driving drum, a transmission band encircling said drivindrum, a vibrating member directl connec to'said transmission band andorming an acute angle with said band on the side toward the drum, andmeans for vibrating said member in such manner that the power strokewhich tensions the said band is slower than the return stroke whichloosens the said band whereb the vibration of the said member causes thetransmission band to rotate the drum.

2. A motor of the character specified comprising in combination arotatln drum, a

transmission band encircling sai rotating drum, a vibrating membercomprising the armature of a buzzer and to which said'band .is attached,means comprising the coils o n.

buzzer for causing the said member to vibrate the anglebetween saidmember and said band measured on the side in contact with the drum beingan acute angle so that the vibration-of sai member sets up both atransverse and longitudinal movement in said band to reduce the waves inthe band which cause t e band to rotate the drum.

3. A device of the character described comprising in combination a drum,a frame, a transmission band encircling said drum, an

armature to which one end of said band is directly secured, saidarmature being mounted on said frame to be capable of vibratory movementtoward and from said drum, an

electromagnet adjacent said armature and adaptedl when suitablyenergized by a pulsating current to vibrate the said armature and to setup waves in the said transmission band, said band extending toward thedrum at an acute angle to said armature whereby the vibration of thesaid armature produces both lon 'tudinal and transverse waves in thesaid and to drive the said drum.

4. A. motor comprising in combination a driving drum, a flexibletransmission member encirclingea portion of' the drum, a vibrating mem rmounted upon a spring and movin toward and from said drum, one end ofsai transmission member being connected to said vibrating means andextending from said means at an angle in a lane substantially atright-angles to the vi ration of sald means in such manner that thevibration of said means acts directly on the end of said band, andanchorin means for the other end of said band, sald angle being an acuteangle toward the drum whereby the band is drawn moreclosely around thedrum when the member moves away from the drum and is partially releasedfrom the lrum ywhen the member moves toward the rum.
